All 3 stack traces belong to the same session and occurred in sequence. The last 2 are consequences of the first and I doubt they have anything useful. The first one shows that one of your forms was begin destroyed (BSVisualizzaCedForm, BSStampaCed1Form or BSStampaCed2Form ??). During the release of these forms something caused an AV. Anything unusual about the destruction of one of the forms?
